CVE-2025-49536 is a high-severity security vulnerability affecting multiple versions of Adobe ColdFusion, specifically versions 2025.2, 2023.14, 2021.20, and earlier. The vulnerability is classified as Incorrect Authorization (CWE-863), which means that the software fails to properly enforce access control policies, allowing unauthorized users to bypass security restrictions. In this case, a low-privileged attacker can exploit the flaw to bypass security features and gain unauthorized access to sensitive ColdFusion resources or functionality. Notably, exploitation does not require any user interaction, increasing the risk of automated or remote attacks. However, the vulnerable component is restricted to internal IP addresses, which limits exposure primarily to attackers who have some level of network access within the internal network or VPN. The CVSS v3.1 base score is 7.3 (high), reflecting the vulnerability's significant impact on confidentiality and integrity, with no impact on availability. The attack vector is adjacent network (AV:A), requiring low attack complexity (AC:L) and low privileges (PR:L), but no user interaction (UI:N). The scope remains unchanged (S:U). Although no known exploits are currently reported in the wild, the vulnerability poses a serious risk due to the potential for unauthorized access to critical application components. Adobe has not yet published patches or mitigations at the time of this report, so affected organizations must be vigilant and consider compensating controls.

For European organizations, the impact of CVE-2025-49536 can be substantial, especially for those relying on Adobe ColdFusion for web application development and deployment. Unauthorized access resulting from this vulnerability could lead to exposure of sensitive business data, intellectual property, or customer information, violating data protection regulations such as the GDPR. The integrity of applications and data could be compromised, potentially enabling attackers to manipulate application logic or escalate privileges further within the network. Since ColdFusion is often used in enterprise environments for critical business applications, exploitation could disrupt business operations indirectly by undermining trust and requiring costly incident response and remediation efforts. The limitation to internal IP addresses reduces the risk of direct internet exploitation but increases the threat posed by insider attackers or external attackers who have gained internal network access through other means (e.g., VPN compromise, phishing). This makes network segmentation and internal access controls critical. The absence of user interaction requirement means attacks can be automated and stealthy, increasing the likelihood of unnoticed exploitation.

Given the lack of available patches at this time, European organizations should implement the following specific mitigations: 1) Restrict internal network access to ColdFusion servers strictly to trusted administrators and systems using network segmentation and firewall rules, minimizing the attack surface. 2) Monitor internal network traffic for unusual access patterns or attempts to reach ColdFusion components from unauthorized internal hosts. 3) Employ strict access control policies and review ColdFusion user privileges to ensure least privilege principles are enforced. 4) Enable detailed logging and regularly audit logs for suspicious authorization bypass attempts. 5) If possible, temporarily disable or restrict vulnerable ColdFusion features or components that handle internal IP-based access until patches are available. 6) Use multi-factor authentication (MFA) for all administrative access to ColdFusion servers to reduce risk from compromised credentials. 7) Prepare incident response plans specifically addressing unauthorized access scenarios in ColdFusion environments. 8) Stay informed on Adobe’s security advisories and apply official patches immediately upon release.
